Inventor UNITED STATES SELLMAR M. JAGOBY, OF NEW YORK, N. Y.

DUST-COLLECTOR.

Application filed September 11, 1917.

To all re/10m it may concern Be it known that I, SELLMAR M. JAooBY, a citizen of the United States, and resident of the borough of Manhattan, in the city and State of New York, have invented a new and useful Improvement in Dust-Collectors, of which the following is a specification.

.My invention relates to improvements in collectors for dust and other light material bodies having novel means for collecting and assembling matter incident to the operation to which it may be applied.

one of the objects of this invention is to provide a device which will by suction draw away from the work all foreign matter floatingin the air and deposit the same in a chamber. 1

Anotherobject is to provide a device having a dustreceiving chamber which may be readily cleaned of the matter collected therein without disturbing the machine with whichit is operating.

Another object is to provide a device which is portable and capable of a wide range of use.

Another object is to provide certain improvements in the form, construction and arrangement of the several parts whereby thea-bove and other named objects may be effectively carried out. I A practical embodiment of my invention is represented in the accompanying drawings in which, v Figure 1 represents improved collector.

2 represents a side elevation of the same. I

Fig. 3 represents a detail vertical section taken in the plane of the line III-III of Fig. 2, looking in the direction of the arows .1

Fig. 4: represents a longitudinal vertical a plan view of my central section.

, Fig. 5 represents a detail vertical section taken in the plane of the line V-V of Fig. 2,and 7 I, Fig. 6 represents an enlarged detail vertical section of one hinge member of the hood, taken in the plane of the line VI-VI of Fig. 5.

The device herein shown and described for the purpose of illustration is intended and designed more particularly for use in connection withfurbeating machines, to be associated therewith for taking up and re- Specification of Letters Patent.

Patented Mar. 15, 1921. Serial No. 190,747.

moving the dust and other foreign matter from the articles being beaten, and is provided with a receiving chamber for the dust .and foreign matter and exhausting air a. main casing 1, open at opposite ends,

a receiving chamber 2 secured to one of the open ends and a hood 3 arranged to cover the other open end and be swung away therefrom.

A suction fan 1 is mounted on a shaft 5 journaled in brackets 6, 7, in the casing 1, and is rotated by means of a belt 8 which connects a pulley 9 on the shaft 5 with a pulley 10 carried by the shaft 11 of a motor 12 secured to the top of the casing.

The receiving chamber 2 is formed with two branches 13, 14, of which the horizontal branch 13 is directly connected to the casing and has a clean-out passage 15 which is closed by means of a cap 16. The cap 16 is removably held in position to close the passage 15 by oppositely disposed hooks 17 on the can which engage oppositely disposed pins 18 fast on the walls of the passage 15. The mouth of the passage is tightly sealed by means of a cupped washer 19 having a disk of cloth or other similar material 20, which is arranged to be held against the walls of the passage by a spring 19*. While this disk of cloth seals the assage 15 it also serves to arrest the heavier dust or foreign matter passing through the branch and collects it, in a common mass, thus permitting it to be readily removed. The cap is also provided with a handle 16* by which it may be conveniently rotated to engage or disengage the pins and hooks.

The vertical branch 14 is provided, near its upper end, with an annular channel 21, within which the dust of a lighter character may fall and be collected. WVithin the upper open end of the branch i l, there is removably secured a conical strainer 22 of fine mesh wire, upon which is fitted a cover 23 of mus lin, cheesecloth or other suitable material. The apex 24: of this strainer is pointed downwardlyin a position directly over the pars sage 15, so that the dust which strikes the cone will fall and be directed into the passage. The strainer is removably held in the opening of the branch. 14 by means of hooks 25 on the strainer, which engage pins 26 on the branch let, similar to the means employed for locking the cap 16 to the passage 15.

The strainer is also provided with a handle 27, by which it may be conveniently manipulated for purposes of removal.

The hood 3 is open along its bottom to receive the work and it is hinged to the casing 1 atthe top by means of hooked bolts 28 'which engage the reinforced rim 29 of the hood so that it may be swung toward and away from the work, as shown in dotted outline in Fig. 4. The hood is also provided with a window 30 arranged to slide in guides 31 formed in the front of the hood.

The casing having the receiving chamber and hood, is'supported upon legs 32 which arelocked to the casing by clamps 33 having bolts 34:, thus permitting the device to be adjusted vertically on the legs.

In practice my improved dust collector is placed in position over a fur beating or other similar machme with the hood located over the table, as shown in dotted outline in Fig.

i, so that the motor driven fan will exhaust the air from the hood and create a. suction which will draw the dust and loose particles through the fan and casing into the receiving chamber, the lighter particles passing through the branch 13 and upwardly to the conical strainer which separates the dust and air. The lighter particles which float upwardly and do not strike the strainer, will pass into the annular air chamber and rest there, while the heavier matter will fall from the strainer into the passage 15. The air thus drawn into the receiving chamber readily passes through the muslin covering of the strainer to external atmosphere while the dust will be collected upon thesurface of the fabric.

From. time to time the strainer may be readily removed and the dust cleaned therefrom. The dust may be removed from the air channel through the opening for the strainer and the dust collected in'the branch 13 taken out through the clean-out passage 1.5., by the removal of the cap 16.

It is obvious that variouschanges may be resorted to in the form, construction and arrangement of the several parts without departing from the spirit and scope of my invention; hence I do not intend to be limited to the details herein shown and described except as they may be specifically included in the claims. I

lVhat I claim is:

1. A dust collector comprising, a receiv ing chamber provided with vertical and horizontal branches, a strainer suspended "from the top of the vertical branch, a cleanont passage in the horizontal branch. in vertical alinement with the strainer, a hood, a tubular casing horizontally disposed between the horizontal branch andthe hood, and a suction fan insaid casing in open communication with the chamber and hood.

2 A dust collector comprising, a receiving chamber provided with 7 vertical and horizontal branches, a removable strainer suspended. from the top of the vertical. branch, a clean-out passagein the horizontal branch in vertical alinement with the strainer, a hood, a tubular casing horizontally disposed between the horizontal branch and the hood, and asuction fan in said casing in open comlniuiication with the chamber and hood. 7
